SyncBoost
by mccmcaozr
SyncBoost cuts out server-side hopper polling that does nothing while a hopper is empty, for servers that run many hoppers.
What it does
A hopper that holds no items still gets checked by the server every tick, and each check costs some work. SyncBoost skips those checks while the hopper is idle. After a hopper meets its condition, the mod leaves it alone for only two ticks, and the hopper's transfer cooldown is kept at 0, as in vanilla. Container GUI synchronization is left entirely vanilla, so the screens behave as they normally do.
The mod is aimed at server owners who want less tick work from hoppers. The server and every player need the mod installed. Files are published for Fabric, Forge and NeoForge, covering 16 release versions 1.21 – 26.2, and the latest builds are 1.0.0 for 26.2 in the beta channel. The code is not open source and is released under All rights reserved.
Key features
Idle hopper skipping
Hoppers with nothing to move are not polled every tick, which removes work the server would otherwise repeat.
Short resume window
After a hopper meets its condition, polling resumes after two ticks, so transfers are not held back for long.
Vanilla cooldown kept
The hopper transfer cooldown stays at 0, matching the value Mojang uses.
Vanilla container screens
Container GUI synchronization is not changed, so inventories and screens behave as they do without the mod.

What the author says
SyncBoost optimizes meaningless server-side hopper polling when idle. Container GUI synchronization is left entirely to vanilla to ensure gameplay correctness.
